Modeling and optimization of hybrid electric vehicles
Özden, Burak Şamil; Ünlüsoy, Yavuz Samim; Department of Mechanical Engineering (2013)
The main goal of this thesis study is the optimization of the basic design parameters of hybrid electric vehicle drivetrain components to minimize fuel consumption and emission objectives, together with constraints derived from performance requirements. In order to generate a user friendly and flexible platform to model, select drivetrain components, simulate performance, and optimize parameters of series and parallel hybrid electric vehicles, a MATLAB based graphical user interface is designed. A basic siz...
Assessment of impacts of electric vehicles on low voltage distribution networks in Turkey
Temiz, Armağan; Güven, Ali Nezih; Department of Electrical and Electronics Engineering (2015)
The number of Electric Vehicles (EVs) has reached a substantial value all over the globe due to economic and environmental factors. The increasing penetration of EVs to the distribution grids urges the requirement to investigate the impacts of EVs on the planning and operation of distribution networks. Despite the fact that there are numerous studies discussing the impacts of EVs on distribution grids, a particular study concerning the Turkish distribution networks does not exist. Therefore, this study focu...
On the parametric and nonparametric prediction methods for electricity load forecasting
Erişen, Esra; İyigün, Cem; Department of Industrial Engineering (2013)
Accurate electricity load forecasting is of great importance in deregulated electricity markets. Market participants can reap significant financial benefits by improving their electricity load forecasts. Electricity load exhibits a complex time series structure with nonlinear relationships between the variables. Hence, new models with higher capabilities to capture such nonlinear relationships need to be developed and tested. In this thesis, we present a parametric and a nonparametric method for short-term ...
Analysis of sinusoidal and helical buckling of drill string in horizontal wells using finite element method
Arpacı, Erdoğan; Özbayoğlu, Evren; Department of Petroleum and Natural Gas Engineering (2009)
The number of horizontal wells is increasing rapidly in all over the world with the growth of new technological developments. During horizontal well drilling, much more complex problems occur when compared with vertical well drilling, such as decrease in load transfer to the bit, tubular failure, tubular fatigue and tubular lock-up. This makes selection of appropriate tubular and making the right drill string design more important. As the total compression load on the horizontal section increases, the behav...
